We are excited to release a developer preview of the AWS Command Line Interface, a new unified tool to manage your AWS services. With just one tool to download and configure, you will be able to control multiple AWS services from the command line and automate them through scripts. This first release supports 12 services, including Amazon EC2, Auto Scaling, Elastic Load Balancing, Amazon SQS, and Amazon SNS, with upcoming support for others. Since this is a developer preview, we are also looking for feedback from the community to help shape its design.
